Hi all, After a couple of very helpful conversations at the IETF meeting in Vienna, we published -01 of the Alternative Server Address Frames draft:
https://datatracker.ietf.org/doc/draft-munizaga-quic-alternative-server-address/01/ The frame format has changed. An ALTERNATIVE_ADDRESS frame now advertises the complete set of available server addresses, indicating whether an address is preferred over the current path or is intended as a backup. The purpose remains to let a server advertise alternative addresses to which the client can migrate. NAT traversal and hole punching remain out of scope, though I expect my NAT traversal draft to use this draft as a building block. Cheers, Marten
